I'm not one who's fallen for all those exotic snake oil spark plugs, but these plugs are making a big name for themselves in the turbo/supercharged mustang world. If you go to the home page and read the technical articles, you can see they've really done their homework. The one with NO ground electrode is crazy! Less prone to fouling, you can have a heat range high enough to prevent fouling, yet at the same time decreases pre-ignition, and all sorts of interesting stuff. Im not ready to go buy some yet, but if anyone else out there has gotten some good results, maybe Ill bite. Their designs seem to keep an uninterrupted flame front in mind. No need for indexing plugs or anything.
